Be it known that'I, CHARLES HARVEY, of Tarrytown, in the county of Westchester, and State of New York, have invented a new and useful improvement in Heads or Ferrules of Propelling Ropes or Cables; and I do hereby declare that the following is a full, clear, andcxact description thereof', which will enable others skilled in the art to make and use the saule, reference being had to the accompanying drawing, forming part of this speciiication, in which drawing- Figure l is a central longitudinal section of my. improvement.

'Figure 2 is aside elevation.

Figure 3 is a cross-section through the axial line ofthe vertical roller`B.

This invention relates to propelling apparatus for moving or propelling railway cars or other vehicles, or towing vessels, where a rope or cable that is kept in continual rncition is used for moving or propelling ears, vehicles, or vessels.

The invention consists, among other things, in a novel inode ot1 constructing and 4uniting to each other the several parts of heads or ferrules of propelling ropes, and of connecting such heads or fcrrules to such ropes; also, in means' for preventing friction between the ferrules and the sides of a trough or guiding channel in which the propelling rope or cable moves, such,for instance, as that described in lmy Letters Patent issued May 8, 1866, and nntedated April 6, 1856; also inA means for preventing the errules from turning in such trough cr channel. Y

The letter A designates a propelling rope or cable, and A one of the heads or ferrules which e'ect connection between the rope or cable and the cable clutch or other grappling device projected from a car, as specified in my said patent. The forward conical part of the ferrule, which is immediately in contact with such clutch, is marked 0, the red line marking the place of the joint between its several sections when the conical part of the ferrule isrnade with joints, as specied in said patent. From the base or rear portion of the said Ipart O extends a link, G, whose'rear end is made spherical, as at H, to form a universal joint with the part D ot' the ferrule,.so as to make the fcrrule capable of being bent out of a straight line, as when turning a curve or anglo. The rear portion N of the ferrule isa hollowconical coupling-shell, N, having a bail projecting from its base, through which bail a hook, hi, or other suitable fastening-device is passed to form a connection with the other portions of the ferrule. When a hooklike M is used theA opening of the hook may be closed by a strand of wire or other device to prevent the release of the bail. The shank of the hook has a spherical end, L, which is enclosed within a socket in the rear end ot' the part D of the ferrule so as to forni a Vflexible or universaljoint similar to that at the forward end of the fcrrule. The rope or cable is connected with the ends ofthe ferrule by means of conical heads Q Q", which fit Within conical cavities formed in the parts .O and N. The part D consists of a frame, made in this example in two sections, marked 1 and 2, which are held together by bolts I I, the adjacent sides of each section, at its ends, having formed therein scmispherical cavities which constitute sockets for holdingwthe spherical ends ofthe link G and the hook M,respcctively, when the sections are united. This construction and arrangement permit the ends of the ferrule to be bent out of line with each other and with the rest of the ferrule without endangering their connections. The middle portions ofthe sections of frame D are cnt out or shaped so as to produce, when the sections are brought together, a vertical opening or mortise, which contains thevertical anti-friction roller B, said rollcrB being made in the form of a zone with depressed or concave sides for the purpose both of providing places in or at the sides thereof for lateral anti-friction rollers and of making the anti-friction surface of such roller B concentric or nearly concentric with the part of the cable guide with which it comes in contact, so that the head or ferrule, or its frame D, may roll sideways or oscillate without preventing the said spheroid from fulfilling its oilice of an anti-friction rolling surface to said head or ferrule.' This roller is of greater diameter than the frame, and its circumference projects both above and below the said frame s0 thatno other part of the frame will come in contact with the lower and upper sides. of the channel described in my said patent, in which the rope or cable travels. The like result is accomplished.

for the sides of the frame by means of lateral anti-friction rollers E E, placed in Seuil-spherical sockets ff, formed in said sides, and turning on axes which are at right angles with the axis of vertical roller B. The sockets ff are at points opposite the concavity of the large roller B, and their convex sides form the bearings of the axis C of that roller. `The journals of thelateral rollers E E Kturn in bearings provided in the sides of the sockets ff, as shown in figs. 2 and 3, and the circumference of they rollersiprojects bcyond'the sockets far enough to prevent contact between the solid parts of the sides of the frame D and the guiding channel before mentioned, when such frame oscillates from side to side. The roller B is wide cnoughto reach across any openings made in the upper or lower-sidV f of such guiding channel when the ferrule A or the part which carries the roller is in a vertical position when it is tilted over to one side or the other the corresponding roller E comes in Contact with the guiding channel andv takes up or prevents friction between the `ferrule and such channel. I have provided means'forfprcvcnting the turning of the frame D in the guiding channel of my said patent by placing a yielding finger, P, on the upper side of/thc frame so that it canproject upward through the top opening of such chauneLgThe said finge: is surrounded by an anti-friction roller,

3, and it is connectedto the frame by placing its"1ower end in a mortisc, J, across which the hinder bolt I passes. The lower end ofthe finger terminatcsin a curved Spring, fastened or let into a slot in a square collar, R, about which the spring is bent, as shown in iig. 2, the collar being placed on that part of the bolt (also made square at that place) which lies in said morti'se. The mortisc is extended baekward,f'as shown in dotted outline in' iig. 2, to permit the finger to lio prostratc, or nearly prostrate, against the rear end of the frame when the said finger is forced downwards and backwards by any obstacle.- Such an obstacle 'will occur when the coupling-clutch of my said patent, that connects a car to the rope or cable A,.is disconnected l orf stationary while the rope or cable is in motion'. In passing such a clutch the finger will be pressed bacl'rwards thereby, and when it has lpassed the clutch the force of the springK will restore it to-an up1ight position so that it 'can project into or through the top of said cable trough or guiding channel,`as before explained.

Among the advantages which result from the construction and arrangement above setfforth is the'flcxibility or capability of bendingof the ferrule A at the places where its partsvarc joined to each other and to the'.

ends of the rope A. Another advantageis the facility which is obtained in uniting the several parts of the ferrule by making the part D in longitudinalsections 1 2, and securing the vertical roller B and thejoints I-I L by placing them in their appropriate places in one sectionand then bringing the sections togetherv and fastening the bolts I.

Having thus described myinvention, what I claim, and desire to sceureby Letters Patent, isI 1. I claim the combination of the lateral rollers E E with the large roller B, the axis ofthe latter being at a right angle with the axes of the former, substantially as shown. .I

2. I also claim the ferrule A composed of a conical forward part, O, a frame D, and a rear part, N, the several parts b eing connected by jointsv which permit of lateral motilouof such parts, substantially as set'forth. l 3. I also claim the construction and arrangement of the fcrrulc A `or its bodyor portion that contains the anti-friction rollersiin sections 1 2, substantially as set forth.

.4. I also claim the yielding fing-erA or ferrulc guide P, substantially as set'forth.

5. I also claim the combination of the hook M connected to the part D, as shown, the conical shelf N, and

the conical end Q of the rope or cable A', substantially Ias shown.`

6. I also claim the combina-tion of' the link G, connected to the part D, as shown, by a. universal joint, with the conical forward part O of thc forrulc, substantially as shown. y

The above specification signczl by me thissevent-eenth day of December. i866.
